Rebar has ridges that bind it mechanically to the concrete with friction, it can still be pulled out of the concrete
under high stresses, an occurrence that often precedes a larger-scale collapse of the structure. To prevent such
a failure, rebar is either deeply embedded into adjacent structural members, or bent and hooked at the ends to lock
it around the concrete and other rebars. This first approach increases the friction locking the bar into place while the
second makes use of the high compressive strength of concrete.
